Sadly overlooked, especially in the West where he is largely unknown, Mo Di (Mozi, or Master Mo to his followers) was a man deeply committed to the welfare of others. He believed that mankind should practice what he called "Universal Love" that is, to strive to treat all others as your own family.
This was extremely radical in his time, far moreso than it is today.
Mohists also advocated a non-aggression policy, and argued that only defensive wars ought to be waged.
My only complaint with this edition is that it is incomplete. There are certain chapters that lack translation, and that was a bit frustrating. Still, the price is far lower than Burton Waston's version (which is quite expensive).
At the very least, it is a good introduction to a brilliant thinker.
